Default Please confirm Motor Rules

Can someone please confirm what is the brushless/brushes equivalent of motors? I am trying to make some rules for my club
19T Brushed equals what?
10.5T Brushless equals what?

10.5 is going to officially be classified as mod by next year.....

13.5 super stock = 19turn
17.5 stock = 27 turn

10.5 is or can be a little faster then a 19t. 13.5 can be or is just a little slower then 19t.

We run 10.5 and 19t together. Now everyone has just gone to 10.5 at our track with 17.5 for stock.

In our club we race 19T and 13.5 brushless together and brushless is still faster. The 19T is SPEC motor though and no modifications are allowed, it's LRP V10 Spec3 19x2.

I can't run the speeds that the 13.5 guys run with my 19T brushed motor on our track's outdoor course. Thing is, my car is heavier (TC3 and its a used 19T) and I'm using NiMH against their LiPos and pretty-new setups (XRay, LiPO, 13.5 newer stuff).

sounds like you should consider running LIPO's and make sure you tune your motor ,, cut com / replace with better brushes clean everything and bearings ... the Lipo will take away some weight .. You should be right there .. Ive ran 19t brush motors and they were faster then 13.5 ....

According to roar:

17.5 = 27t
13.5= in between the two
10.5 = 19t

This year, superstock was 19t/10.5. Next year it changes to 13.5 only.

Ive found these comparisons to be very accurate. Anybody who thinks 13.5 is faster than 19t had never had a good 19t

Man ,not this debate again........ I will say it depends on the track.17.5 favors smaller tracks.27t brushed is a little quicker on larger tracks.

I found the opposite problem, my 13.5 in a TC3 does not have the speed. But I know the problem is because the gearing is not tall enough. A 72 spur with a 28 pinion is the highest I can gear, so I am now ordering spurs in the 60 tooth range.
